class MyDataObject extends DataObject {

    ...

    private static $has_many = array(
        'OtherDataObjects' => 'OtherDataObject'
    );

    function getCMSFields() {
        $fields = parent::getCMSFields();

        if ($gridField = $fields->dataFieldByName('OtherDataObjects')) {
            $gridField->getConfig()
                ->removeComponentsByType('GridFieldExportButton');
        }

        return $fields;
